Abstract
A 57Fe Mössbauer search for field-induced magnetic order in optimally doped Ba(Fe1−xCox)2As2 in fields of up to 6 T showed no changes that could be attributed to field-induced order. We also observed no difference between the normal (30 K) and superconducting states (5 K). Any field-induced order is certainly less than 1% of the order present in the parent BaFe2As2.
